After all, the universe required ten billion years of evolution before life was even possible; the evolution of the stars and the evolving of new chemical elements in the nuclear furnaces of the stars were indispensable prerequisites for the generation of life.
John Polkinghorne

Although every step must be taken to protect against a chemical or biological attack in America, our nation would survive the use of those weapons as we did when anthrax was mailed to our Capitol and other targets.
Adam Schiff

And they will tell you unequivocally that if we have a chemical or biological attack or a nuclear attack anywhere in this country, they are unprepared to deal with it today, and that is of high urgency.
Warren Rudman

But as population became denser, the natural chemical and biological recycling processes became overloaded, calling for a redefinition of property rights.
Garrett Hardin

But in fact, when you try to model that on a computer you find that because of the very structure of matter and of the chemical bonds that are the basis of every organism, evolution is not random at all. It will tend to follow certain paths.
Kevin Kelly

But the nature of my main work in chemistry can be better represented by more than 280 English publications, of which roughly 200 concern the theory of chemical reactions and related subjects.
Kenichi Fukui

But the prospects of designing chemical plants for industrial scale chemical processes seemed far less interesting than the chemical events that occur in biological systems.
Paul Berg

By recognizing that the chemical atom is composed of single separable electric quanta, humanity has taken a great step forward in the investigation of the natural world.
Johannes Stark

Computer photography won't be photography as we know it. I think photography will always be chemical.
Annie Leibovitz

Don't let that weapon technology proliferate. Don't let Saddam Hussein get capability for nuclear or chemical weapons, because he's already shown a willingness to use any weapon at his disposal.
John Sununu

Elements which are similar as regards their chemical properties have atomic weights which are either of nearly the same value (eg. Pt, Ir, Os) or which increase regularly (eg. K, Ru, Cs).
Dmitri Mendeleev

Every chemical reaction has a transition state.
Derek Harold Richard Barton

Every day Saddam remains in power with chemical weapons, biological weapons, and the development of nuclear weapons is a day of danger for the United States.
Joe Lieberman

Everybody's youth is a dream, a form of chemical madness.
F. Scott Fitzgerald

Finally, as the digestive canal is a complex system, a series of separate chemical laboratories, I cut the connections between them in order to investigate the course of phenomena in each particular laboratory; thus I resolved the digestive canal into several separate parts.
Ivan Pavlov

Football tactics are rapidly becoming as complicated as the chemical formula for splitting the atom.
Jimmy Greaves

For me, first, it's finding quiet in my life - and I do that through yoga and meditation. It's also been a matter of changing the way I eat, because I think what we eat can inform who we are; food is a chemical and a drug to a certain extent.
Mariel Hemingway

For their discoveries concerning the chemical structure of antibodies.
Rodney Robert Porter

For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and these can come in the form of electromagnetic waves only from accelerated electric quanta.
Johannes Stark

George W. Bush and Tony Blair had to convince the world that Saddam Hussein represented an imminent threat. Tony Blair lied when he claimed that Iraq could launch a chemical or biological attack within 45 minutes.
Bianca Jagger
